As we enter the second week of January it’s time again to get to know one of Layar’s many great team members. This week we step it up a notch, as we hear from Dirk Groten, Layar’s Chief Technology Officer.

Dirk has been with Layar nearly since the beginning, and helped turned what was once just an app into a platform for third-party developers. Here’s our Q&A with the CTO.

Name, rank and serial number, soldier! Where are you from?

Long story. I was born in Luxemburg and grew up in Luxemburg, Paris, Johannesburg, Geneva and Zurich. Quite a bit of traveling actually, always following my dad where his new job was. My father is from Germany, my mother Dutch and we’ve always spoken French at home.

Living in South Africa as a kid was great and I enjoyed celebrating Christmas on the beach. After we moved to Switzerland, the first time we walked in the mountains and a cow moved behind a bush, I ran away thinking it might be a lion. Swiss wildlife huh?

I have a sister, she’s 18 months younger and has four kids (two girls and two twin boys). She lives in Zurich and the whole family got the Swiss nationality a month ago.

Your education must have been quite hectic with all that moving.

I went to French schools at all the places we lived. The nice thing about the (very centralized) French school system is that the curriculum is exactly the same in all French schools, wherever in the world. So if you move places a lot, like we did, even in the middle of a school year you’ll open the text book in your new school at exactly the same page as you left in your previous school.

At least that transition is easy, although you still need to make new friends and get used to the new teachers. That’s the hardest part of being dragged along around the world as a kid. After school, I studied physics at the ETH Zurich (Swiss Federal Institute of Technology) and did a PhD in physics at Leiden University here in the Netherlands.

So what do you do here at Layar?

I’m CTO at Layar, so I manage the entire development team and R&D. Lately I’ve been very busy recruiting new developers for our teams in Amsterdam, Kiev and Donetsk. Also with our current growth I’ve been structuring our processes quite a bit.

We’re not a startup with 3 developers anymore so we’ve had to make some more formal agreements on our development process. During a typical day I have many meetings where we decide on new features, APIs and technologies for Layar.

And before Layar?

I used to work at KPN Mobile, a mobile telecom operator. I was involved in specifying the handsets and platform for i-mode, the first mobile internet services in Europe. It didn’t turn out to become a big success, the iPhone was the breakthrough for mobile Internet.

But I’ve been hooked up on checking my mail, searching stuff on Google and checking weather and the public transport time tables on my mobile phone since 2001 already. i-mode worked pretty well actually!

What do you like most about working at Layar?

The constant changes are the most fun part. Every month new faces, new ideas and new technologies. We’ve got to follow our instinct closely, as this is unchartered territory.

There isn’t a text book that can tell you what your next move needs to be, as a rational guy that usually bases decisions on good argumentation, I was surprised to see how strong our instincts are and how they keep us sharp.

And finally, what do you enjoy outside of Layar and technology?

I love the mountains, having spent more than 15 years in Switzerland. Mountain biking, skiing and trekking are my favorite activities. I’ve walked two weeks on the Pacific Crest trail in Washington and that’s been one of the most exhilarating experience due to the pristine nature. But also climbing the Mont Dolent on skis or the Mont Ventoux by bicycle are achievements I’m proud of.
